Mark Twain once observed
that a lie can travel halfway around the world while the truth is still putting
on its shoes and nowhere is that axiom more true than in the world of firearms,
especially since the advent of the Internet. A word then, perhaps, about the
inherent “weakness” of small ring, non-98 Mauser actions, including the 91, 93,
94, 95 and 96 models manufactured for use by Spain, Argentina, Sweden, Chile,
Turkey and many other countries around the world. This non-issue has been
written about by illustrious gun scribes and aped by ignoramuses far and wide
for decades.

“The steel used by the
Spaniards is considered to be soft,” one know-nothing opined on a web page
recently, perhaps not realizing that all of the true 1893’s were built by
Mauser, Ludwig Lowe or DWM in Germany. The truth is, while the earlier actions
are indeed not as strong as the rugged M-98, they are plenty strong enough when
used as intended. For years, the Swedish firm of Husqvarna turned out fine
sporters based on 96 Mauser actions in .30-06 caliber.

Thousands of beautiful custom
sporters in useful calibers like 7x57mm Mauser, 257 Roberts, 8x57mm Mauser, .35
Remington, 9.3x57, 6.5x55 Swedish and the .300 Savage and .250-3000 Savage have
been turned out using small ring actions, which have a number of advantages
some believe offset the fact that they can’t be chambered for the .458
Winchester Magnum.

In truth, the myth about the
weakness of the earlier Mauser actions coincided almost perfectly with the
foundation of the Sporting Arms and Ammunition Manufacturers’ Institute
(SAAMI), a private organization established at the behest of the United States
government. This was in 1926, more than a generation after Mauser began turning
out smokeless powder repeating rifles.

Currently, SAAMI dictates
that ammunition sold in America for most of the calibers mentioned above
generate no more than 50,000 psi when fired, a mandate that has led to the
underloading of popular European calibers like the 7x57 and the 8x57, as well
as some American calibers. The .257 Roberts very nearly became extinct because
of SAAMI pressure standards set arbitrarily and absurdly low due to the large
numbers of small ring Mauser and other surplus actions used as the basis for rifles
built for the former wildcat cartridge.

In its original military
loading, the 7x57mm cartridge produced an average pressure of 50,370 CUP when
fired through the M93 Spanish Mauser rifle, according to J.M. Whittemore’s 1899
treatise, Report Of Test of Mauser Arms And Ammunition Relative To Pressures
And Velocities. Whittemore drew from the work five years earlier of the
Spanish ballistician Salvadore Cardenal, whose 1895 report for the Spanish
government reached the same conclusions.

However, SAAMI has published
a Maximum Average Pressure of only 46,000 CUP for this round, which leads to
the possibility that commercial rifles built to SAAMI standards may not be
designed to withstand the powerful military cartridges intended for the more
robust pre-98 Mauser designs.

It’s a well known fact that
older military cartridges loaded for sale in Europe are hotter than their
American counterparts, but it isn’t generally known why. Certainly, the
European governments care as much as the Americans about citizens dying from
catastrophic firearms failures.

Instead of SAAMI, the
Europeans employ C.I.P., the Permanent International Commission for Firearms
Testing. A far more independent organization, the C.I.P. was founded in 1914
and does not answer to corporate American or European gunmakers. According to official
C.I.P. guidelines, the 7×57mm case can handle up to 390 MPa (56,564 psi) piezo
pressure. In C.I.P. regulated countries, every rifle/cartridge combination has
to be proofed at 125% of this maximum C.I.P. pressure to certify for sale to
consumers.

By contrast, SAAMI specifies
a far lower maximum pressure of 46,000 CUP or 51,000 psi. Although this lower
specification is due to concern about the allegedly weaker actions of the older
Mauser 93 and 95 rifles, this anxiety is misplaced, as the original ammunition
developed for, and issued with, the M-93 Spanish Mauser produced an average
pressure of 50,370 CUP in those rifles. Since the Spaniards continued building
M-93s themselves into the 1950s, continued C.I.P. proof testing would have
uncovered any inherent weakness in the action.

Some might argue that the
century old steel in original 1891, 1893, 1895 and 1896 Mauser actions is
somehow not as strong as it was when first manufactured. In the case of rusted,
pitted, dented or otherwise damaged examples, this would indeed be the case. Anyone
who thinks fine steel somehow degenerates in ways not apparent to the naked eye
over a period of time as brief as 100 years would do well to research Japanese
swords turned out on primitive hand forges as early as the 13th and
14th centuries. The pristine blades are as strong as they ever were,
in many cases stronger than steel blades turned out today using modern
technology.

I suppose I’m thinking about
all this today because, on the table in front of me, sits a Spanish M-93
action, turned out by Ludwig Lowe of Berlin in 1896. A quarter of an inch
shorter and two ounces lighter than the large ring M-98 action, it remains, I
believe, the perfect platform for the 7x57mm cartridge, the round for which it
was specifically designed 120 years ago.

I’ve decided to go ahead with
the project, a lightweight sporter in the classic configuration, and have just
spent the morning happily ordering a new stock and barrel, an adjustable
trigger and bolt safety, a set of iron sights, scope bases and rings. I know a
gunsmith near here in the Santa Monica Mountains who can put it all together
for me and in a few months I’ll be the proud owner of a custom 7x57 capable of
taking anything I might find out here in the west, from coyotes to elk, so long
as I do my part.

One thing is certain. No
matter what ammunition I use, I’ll be a lot more concerned about my own
strength and stamina than I will about that of the Mauser action Lowe turned
out 60 years before I was born.
